CITI: These 16 Companies Are The World Champions Of Energy

Citi has declared 16 energy firms as "global champions" based on an array of financial metrics and returns trends.

In a new massive 78-page report, a team of Citi analysts led by Alastair Syme identified the energy companies that enjoy the best growth prospects in the world.

They each have a market cap of at least $3 billion, a top 3 market share in a third of of their businesses, and significant revenue from outside their respective home markets. They all have a "track record of delivering" on financial performance.

Citi's team admits some determinations were "a bit more art than science," especially looking at market share, which can signal a number of different things about a company.
